Get started with your Flow Keyboard for Mac®

Welcome to your Flow Keyboard

We’ve completely reimagined the keyboard to keep your ideas flowing. The Flow Keyboard uses a rechargeable battery and Bluetooth® technology to connect wirelessly–wherever you work. This guide shows you how to use your Flow Keyboard, including pairing, setting up your workspace, customization, and recharging the battery.

Designed to move, just like you

We know there is no one size fits all. That’s why the Flow Keyboard is designed to move with you throughout the day. Your workspace should be designed around you. So position your Flow Keyboard wherever it feels most comfortable. Need to adjust? No problem. The split design allows you to open the shoulders. Rotate the keyboard to keep the wrists happy. Combine with other NUIO Flow™ products to complete your system. Work is dynamic and now your tools are too.

Backlighting

Your Flow Keyboard features key and legend backlighting that allows you to work in low to no light environments. The backlight is controlled with the (F3/F4) keys. Use the (F4) key to turn on the backlight or increase it’s brightness. Use the (F3) key to decrease the brightness or turn off the backlight.

Customize your Flow Keyboard

  1. Choose Apple menu > System Settings, then click Keyboard.
  2. Customize the keyboard by adjusting any of the global settings in the Keyboard menu.

Rename your Flow Keyboard

The Mac gives your NUIO Flow Keyboard a default name the first time you pair it. You can rename it in Bluetooth preferences.

To rename your keyboard:

  1. Choose Apple menu > System Settings, then click Bluetooth.
  2. Control-click your Flow Keyboard, then choose Rename. Alternatively you may click on the "info" icon on the right side your keyboard.
  3. Enter a name and click Done.

Recharge the battery

To recharge the battery, use the USB-C Cable that came with your keyboard. Plug the end with 2 USB-C ports into each half of your Flow Keyboard, and the single USB-C end into a USB-C port on your Mac or a certified USB-C power supply that supplies voltage at a minimum of 5V and 1.5 amps. The Keyboard Indicator light on the back of the keyboard will flash green to indicate that it is charging.

To check the battery status and levels, choose Apple menu > System Settings, then click Bluetooth. The battery status is shown in under the Flow Keyboard device and it displays connection status and the lowest battery level of the two batteries on the Flow Keyboard.

Alternatively, you may check the battery level by pressing the Battery Indicator button on the bottom of each keyboard. The button lights up to indicate the level of charge:

0 lights = 0% charged
1 light = 1% - 20% charged
2 lights = 21-40% charged
3 lights = 40-60% charged
4 lights = 60-80% charged
5 lights = 80-100% charged

The Flow Keyboard goes to sleep to conserve battery power when you aren’t using it. If you won’t be using your keyboard for an extended period, turn it off to conserve more battery power.

Waking from Sleep

You must press keys on both the right and left keyboards to wake the Flow Keyboard from sleep. To decrease the time to wake, press a key on the right side first, then on the left side.

Remove pairing

Removing a Flow Keyboard pairing is a two-step process.

  1. Choose Apple menu > System Settings, then click Bluetooth. Rollover the existing pairing in the My Devices menu and press the Disconnect button.
  2. Then press and hold the Bluetooth Key on the right NUIO Flow Keyboard for 5 seconds.

Clean your Flow Keyboard

To clean the outside of your keyboard, use a lint-free cloth. Don’t get moisture in any openings. Don’t use solvents, aerosol sprays, or abrasives to clean the keyboard.

Use care when magnets come together

Our products use magnets to aid with positioning and alignment. Because magnets can attract to each other, and other objects – please use care when handling them. Please be aware of the potential pinching hazard that can occur when two magnets come into close proximity or make contact. Magnets possess attractive forces that can cause them to snap together suddenly, creating a pinching effect that may result in injury to fingers, skin, or other objects caught in between. Store them apart or attach to the Deskpad when not in use. Keep them away from children and do not use them for any other purpose than they were designed for - as a positioning tool for NUIO products.

Also, please review our note about possible magnetic interference with medical devices here.
